Free Anti Spam Software

and I try and get on the internet and all kind of crazy porn and warnings about how my computer proformance is being decreased and I think that I have a lot of spam or somethnig its even sayin something about spyware……… I really don’t no to much about computers and I don’t have money to fix it can someone tell me what I can do about this problem that am having and how I can download something for free to fix it I all ready have a anti viris software installed on it tho.

In my dept mail i am receiving lot of spam mails. The sender’s name, subject and content are unique. So I couldnot set filters for that. I am using Outlook Express. Can anyone help me to filter out spam mail coming to my account to a separate folder like spam in gmail or bulk in yahoo.

Groupshield 6 is installed on our Comms Svr running Exchange 2000 Standard Edition. This is the ISA Server and the e-mail gateway. This server forwards E-mail to 3 other Exchange Servers at three separate geographical sites within the local domain. I have spent hours trying to get the best out of the Spam Killer plug in to Groupshield but it is still letting huge amounts of SPAM through (it is trapping a lot also). Im not certain if I need to install additional copies of groupshield on each of our other three exchange servers in the separate OU’s but I have a feeling Groupshield and SPAM killer only work on the gateway server?

Any advice? Maybe there is better Anti SPAM software? A lot of SPAM is being caught but mostly its the Viagra and Penis Enlargement (!) type and not other sorts offering fake watches, business opportunities etc! I can import a blacklist.txt file but im not sure of the layout nor where to download a decent one from. Im hoping there is a web site one!
